DUPLEXy `OIL-WELL lPUMPING( POWER.

Application filed Julyr 3, 192,6. ySerial No. 120,348.

One of the objects of my invention is to of individual wells. y

Another' object of my inventionr is to design a pumping apparatus suitable y'fory the proper pumping of a r:reasonable number source of power. f i

This apparatus is a decided'improvement over myformer apparatus shown in my of wells of different nature, all from oney Number 1,288,008.y f

YVith the foregoing and other objects in view,y my' invention comprisesfcertain novel constructions, combinations, yand arrange# ments ofv parts as will rbe hereinafter fully described, illustra-ted in the accompanying c' drawings, and more particularly pointed 'out iii the appended claims.

In the drawings: 1 a y yFigure 1-is a vertical, central sectional view'ofan apparatus constructed in accordance with' thepresentinvention l 'Figure`2 is a fragmentary,vertical, cen-y tral "sectional view of anr apparatus constructedr in accordance with the present invention, at substantially right angles to they lineon which Figure 1 is taken,and` showy ing the eccentrics in an extended position, whereasinFigure 1, the eccentrics are shown yin what-n'iight be termed a neutral position. .l f l' Figure 3 is a sectional view taken on line 3-f-3Figure 2, and looking in the direction of the arrows.y f

. igure is a sectional view taken on line A15e-.6, Figure 2 and looking in the direction of ,the arrows. f

, iFigure'T is an enlarged fragmentary insidek Vview ofthe belt kwheel showing the manner of connecting the sections of the rim and the means for fastening the outer ends yof the spokes, while Figure- 8 is an edge View of the saine.

.Figure 9y is an enlarged fragmentary 'view of the outside of the rim of the belt Wheel. Figure 10 is an enlarged top plan view ,of the connecting kdevice for the eye bolt, ypipe .support Land anchor 'stay rod, shown also in Figure 1. s f

Referring to the drawings by numerals, 1 is the foundation,preferably formed of concrete or cement, and 2 designates the floor line (Figs. 1 andv 2). Supported upon the foundationl is the primary casting 3. n This casting 3 is provided with a depending hub r4 against the lower end of which iscircular threaded plate 5. -A baseplate 6 is posif tioned ,against plate 5, and by means of screw-like bolts 7, the plates 6 and 5 are casting 3 on the foundation 1. By means of anchor bolts 8, the casting is securely fastened upon the foundation 1. y

yThe stationary vshaft 9 is threaded aty its lower end into plate 5, and upon this shaft 9 are positioned two pressed in bronze bushring plate 11,*whichirests upon the flanged upperyportion 12 of the hub 4. yA drive sleeve 13 is krpositioned upon shaft 9, with the bushing 10 therebetween, and mounted upon this sleeve 13 is the belt `wheel 14, high speed eccentric 15 and lowspeed eccentric 16,. I use the terni high speed with refei= ence to the 'eccentric 15 because it is keyed upon sleeve 1 3 ai'idworks atI a greater speed than the low speed eccentric 16, as eccenapproxiniately rwork at about two-thirds the speed of eccentric 15. y f

An auxiliary adjustable casting 17 is mounted in the primary cast-ing 3, and I use the terinfcasti ng in a generic sense, be.-

cause these castings 3 and 17 might be termed casings or containers. The casting 17 is provided with` a gear receiving groove 18 in which` is positioned ring-like gear 19;,gear 19 being provided with internal teeth clearly Surrounding shaft 9 is abronzel "tric 1G is geared to sleeve 13, so that' it will ioo shown in Figure 6. This gear 19 meshes with the pinion 20, the hub 21 (dotted lines) of which is hexagonal in shape at its bottom end. A ring plate 22 rests upon the upper flanged edge of gear 19 (Fig. 2), and a ring 23is drawnor tightly held `between the depending flange on the outer edge of ring plate V22 and the outer ianged'edge of gear 19 by means of screw bolts 24, so that the ring plate 22 is locked orfastene'dtightly upon the upper edge of the primary gear 19. A cover plate 25 is fastened by screw bolts 26 upon the casting 17 5 this cover plate 25 lreeps foreign substances Vsuch as dirt, dust, and the like from entering the space between the gears, and asthe gears preferably work `in oil, it clearly assists in keeping the oil clean too. An upstandi'ng integral roller lug 27 is formed on the' ring plate 22 (Fig. 2), and mounted upon the roller lug is a tire-like sleeve `28; a ball bearing device 29-is mounted upon the upper end of roller lug 27, 'which roller lug and sleeve 23'entends into theiauniliary or low speed eccentric 16.

` A cover plate 30 is over the'ball bearing device 29 and roller lug` 27, closing theupper end of the opening 31 inthe eccentric 1. The eccentric rings34 and 36 are alike and each is provided with suitable pump rod connections 32. The eccentric hub 16=is bronze hushed and rests in the upper end of This eccentric V16 comprises the pinion 20; the innerrotatable section 33, loosely mountedupony drive sleeve 13, and outer reciprocal section 34. ATherefore,it'will VbeV seen that when the belt wheel 14Sis'rotated, sleeve 13 i will be rotated, resultingin pinion 2O being rotated, which in turn will' rotate gear 19,

and through the roller lug 27, the inner section 31, of eccentric 16 will be rotated slowly, andthe outer section 34 will be slowly recipf rocated for .operating slowly `the pumps of Y certain oil wells.

' The primary or high speed. eccentric 15 comprises inner` rotatable,I section 35 and'V the outer reciprocal election 36-11; is to'be noted that the centralj portion ofdrive sleeve 13 tapers and that theV eccentric 15 and belt wheel 14 are mounted on this tapered portion V(Figs. 1 and12). The eccentric 15 is held tightly ,upon kthe tapered portion of sleeve 13 bymeans of bolts 37, which bolts pass through portions of the hub v33 of the belt wheel 14 and through the hub 39 of the kinner 'rotatable section 35 of said eccentric drawn upon the tapered portion of the sleeve 13 by meansV of screw bolts 40, which bolts extend through clamp ring 41, on sleeve 13, into the' hub 38'of saidk beltwheel 14. ,let in7 split ring 42 is positioned between said clamp ring 41 and drive sleeve 13, fastening these elements together against inde pendent movement. Itis to be understood that power is supplied to the belt wheel 14 and by reason of said belt wheel and eccentric 15 being lreyed at 43 upon the drive sleeve 13, these two elements will be rotated at the same speed, which is much greater than the slow movement of the auxiliary eccentricl.

The belt wheel 14 includes the hub 38 integral with hub plate 44 A(F ig. 4) and fastened on said plate 44, by U-shaped bolts 45, are spokes 46.V The Arim 47 is preferably made in sectionstltigs. 7 to 9) and the abutting ends of these Sections are held together by: plates 43. A ring 49, substantially H- shaped in cross section, is'fastened within the rim, against plates 48 (Figs. 7 and 8), and a plate 50 is placed over and eX- tending in the outer endV of each spoke 45, and eye-bolts 51 extend through plates 59 and Vpart of the ring 49, and a bolt 52 extends through each spoke and the eyes of boltsl, whereby the outer ends of said spolres are securely fastened in position upon ring and 1iin 47. Brace rods 53 have their outer ends fastened to ring 49 and their inner' ends'are fastened to the lower end of hub 33.k yUpper brace rods 54 are fastened at their outer ends to ring 49, and their inner drive sleeve 13.1

The outer end of shaft 9 is suitably formed for receiving a tool such as a wrench rfor assisting in setting or placing the'shaft, with respect to its being screwed into threaded 55 mounted on the upper or outer end of plate 5. Stay leyetbolts or rods 56 have their vrounded ends of block 58, and carried byV the other lor lower end of plates 61 is a second block or sleeve (S3, through which eX-l tends the anchor stay rod 64; this bloclr 63 being retained in position upon plates61` by means of rounded ends 65 ofblock G3. The pipe support 6() can be Vsecured in any suitable inanner upon the ground or toa foundation (not shown). lt is obvious that. each stay rod 5G is provided with one of these supporting vand bracing)` devices, comprising said plates 61, blocks and pipe support 60 and stayrod 64. Y 1t if; to `he understood that said primary asting 3 has a dropped and bracketedhub.` `I`red off center, suflicient toperinit ar toothedjustincnt by turning casting` and locking'thesaine inthe desired posion, for the `proper gear niesh through the medium of the screw bolts G6 2).

Yends are fastened to a ring or annular plate lli sesam This structure provides a ypositive and most simpleadjustment possibleand easy of access. "The way I have shown and described shaft illustrates a structure which is most Substantial and convenient as it isfself centering and permits installing; or removing said shaft at any time desired, without dis turbing any inside parts. f A further advantage of this structure is that it permits true yalignmt-znt yof shaft 9 with respect to the primary casting' cient service. if l It is to be understood that the geargroove 3 and assureslong and eli'i- 18 is what might becalled an eccentrically located bearing for the driven gear 19. Both gears 19"` and 2O operate in a bath ot' oil; thesei gears have wid-e face and helical teeth from` backlash. l

The,ball'bearing'device 29 rolls'in and out on the under face of plate 30 (Fig.y 2),

wh`ch permit perfect and yeasy running, free tsfpurpose being to carry a part ofthey weight ofeccentric 16. c

yThis ,two motion power7 is madepossible f and practical by the gearing, controlling the movement of eccentric i6 and the primary eccentricr operatedy directly by the sleeve 13.

It is to bek understood that I am n'iakinn' no rspecific claim to anytype of means for 'connecting my lec-ceiitrics to well pumpsr4 ant I have only designated the pump connecf tions `broadly bythe numeral 32, my l ventiou being primarily directed to the construction orhookup ofthet-wo eccentrics and ythe belt wheel.` f

ldlliilelhave described the preferred emA`r` krbodnnent ot my inventionk and illustrated the same in the accompanying drawings. certain minor ehangesor alterations may ap-` pear to one skilled inr the art to vwhich this invention relates during the extensive manufactureof the same, and,`I, therefore, re-r serve the right tor malte such alterations for changes as shall fairly fall within the scope ofthcappcnded claims. i
